Cut out all the different sized shapes of the image, then layer them on top of each other with foam pads or silicone adhesive, at a slightly twisted angle, starting with the largest at the base and the smallest at the top, to create a 3D pyramid effect.

This is a traditional decoupage sheet, so scissors are needed!

Web image is watermarked by the manufacturer - the decoupage sheet itself is of course not watermarked.
